Ques. How to delete database objects with "DROP" statements in MS SQL Server?

Ans. To remove all database objects created by previous tutorials, you could just delete the database. However, in this tutorial, you will go through the steps to reverse every action you took doing the tutorial.

Removing permissions and objects - Before you delete objects, make sure you are in the correct database:

USE YourDataBaseName;
GO

Use the REVOKE statement to remove execute permission for Mary on the stored procedure:

REVOKE EXECUTE ON pr_Names FROM Mary;
GO

Use the DROP statement to remove permission for Mary to access the YourDataBaseName database:

DROP USER Mary;
GO

Use the DROP statement to remove permission for Mary to access this instance of SQL Server 2005:

DROP LOGIN [Mary];
GO

Use the DROP statement to remove the store procedure pr_Names:

DROP PROC pr_Names;
GO

Use the DROP statement to remove the view vw_Names:

DROP View vw_Names;
GO

Use the DELETE statement to remove all rows from the Products table:

DELETE FROM Products;
GO

Use the DROP statement to remove the Products table:

DROP Table Products;
GO

You cannot remove the YourDataBaseName database while you are in the database; therefore, first switch context to another database, and then use the DROP statement.
